All I know about the Halloween movies is the name.
I watched the Halo - Forward unto Dawn series a couple days ago. I'm mixed on it - there was plenty that was good about it, but everything that was good, could be swapped into BSG and you wouldn't know the difference. The parts that were Halo were the weakest parts - it went from feeling like BSG academy to another video game movie.
I missed the grunts too.
